Hi, Is it possible you need sunlight to activate vitamin d stored in the body. I ask this as I have been taking supplements but only feel better if I have been in the sun or have been on a tanning bed?

Ask the Vitamin D Council

    No you do not need “sunlight to activate” stored Vitamin D.
    More then likely it could be that you just are not taking enough Vitamin D as a supplement to equal what you make if you go in the sun or tanning bed. People can make 10, 15, 20,000 or more IU in the sunshine or tanning bed in a relatively short amount of time. So I do not know how much you take when you take a supplement but perhaps increasing the amount might help. Also science has proved that the other wavelengths of light also do things for us, so this may also be what makes you feel better.
